以海蜇新生螅状幼体为研究对象，采用实验生态学方法研究了3种高温（室内恒温、夏季常温、夏季高温）、3种饵
料投喂频率（无饵料投喂、每周投喂1次、每2 d投喂1次）及其交互作用对海蜇螅状幼体的死亡率、个体生长和足囊繁殖的影
响，试验持续45 d。试验结果显示：高温条件下，饵料投喂频率显著影响海蜇螅状幼体的死亡率(P<0.05)；而高温、饵料投喂
频率及两者交互作用均显著影响海蜇螅状幼体的相对生长率(P<0.05)；各高温组中螅状幼体生成的足囊数均随饵料投喂频率
的增加而增多；足囊萌发率最多出现在夏季常温-每周投喂1次组，平均为34.34%；饵料投喂频率对海蜇螅状幼体生成足囊数
及足囊萌发率影响显著(P<0.05)，高温及两者交互作用对海蜇螅状幼体生成足囊数及足囊萌发率影响均不显著（P>0.05）。试
验结果表明，尽管高温条件下海蜇螅状幼体死亡率高，但存活的螅状幼体足囊繁殖速度快，足囊繁殖速度随温度的升高而加
快可能是螅状幼体应对高温死亡率增加的一种繁殖策略。试验结果可为提高海蜇育苗技术和准确预报苗种产量提供科学依据。

Canadian Census
**Overview** The data package provides demographics for Canadian population groups according to multiple location categories: Forward Sortation Areas (FSAs), Census Metropolitan Areas (CMAs) and Census Agglomerations (CAs), Federal Electoral Districts (FEDs), Health Regions (HRs) and provinces. **Description** The data are available through the Canadian Census and the National Household Survey (NHS), separated or combined. The main demographic indicators provided for the population groups, stratified not only by location but also for the majority by demographical and socioeconomic characteristics, are population number, females and males, usual residents and private dwellings. The primary use of the data at the Health Region level is for health surveillance and population health research. Federal and provincial departments of health and human resources, social service agencies, and other types of government agencies use the information to monitor, plan, implement and evaluate programs to improve the health of Canadians and the efficiency of health services. Researchers from various fields use the information to conduct research to improve health. Non-profit health organizations and the media use the health region data to raise awareness about health, an issue of concern to all Canadians. The Census population counts for a particular geographic area representing the number of Canadians whose usual place of residence is in that area, regardless of where they happened to be on Census Day. Also included are any Canadians who were staying in that area on Census Day and who had no usual place of residence elsewhere in Canada, as well as those considered to be 'non-permanent residents'. National Household Survey (NHS) provides demographic data for various levels of geography, including provinces and territories, census metropolitan areas/census agglomerations, census divisions, census subdivisions, census tracts, federal electoral districts and health regions. In order to provide a comprehensive overview of an area, this product presents data from both the NHS and the Census. NHS data topics include immigration and ethnocultural diversity; aboriginal peoples; education and labor; mobility and migration; language of work; income and housing. 2011 Census data topics include population and dwelling counts; age and sex; families, households and marital status; structural type of dwelling and collectives; and language. The data are collected for private dwellings occupied by usual residents. A private dwelling is a dwelling in which a person or a group of persons permanently reside. Information for the National Household Survey does not include information for collective dwellings. Collective dwellings are dwellings used for commercial, institutional or communal purposes, such as a hotel, a hospital or a work camp. **Benefits** - Useful for canada public health stakeholders, for public health specialist or specialized public and other interested parties. for health surveillance and population health research. for monitoring, planning, implementation and evaluation of health-related programs. media agencies may use the health regions data to raise awareness about health, an issue of concern to all canadians. giving the addition of longitude and latitude in some of the datasets the data can be useful to transpose the values into geographical representations. the fields descriptions along with the dataset description are useful for the user to quickly understand the data and the dataset. **License Information** The use of John Snow Labs datasets is free for personal and research purposes.
